Hydrocarbon Geochemical Indices Selection by Grey Correlation Analysis

Abstract

Abstract: With the development of petroleum geochemistry and improvement of modern analytical technology, more and more biomarker parameters of petroleum are available.This paper selects 30 biomarker indices from 27 oil samples in Nanyang depression on the basis of some well known biomarker indicators and using the grey correlation analysis, and classified into three types related to original organic matter, organic matter maturity and both of them.Such new geochemical indices as m(β-drimane)/m(α+β-drimane),m(βα-pregnane)/m(αβ-pregnane), m(oleanane)/m(gammacerane), m(8,14-secohopane C29)/m(C30) are proposed in this paper.They will support the in-depth study of the molecular parameters in geochemistry.

Key words: molecular biomarkers, biomarker parameters, grey correlation analysis, Nanyang depression
